3 Claims.

This invention relates to an improvement in mixers.

The object of this invention is to provide a portable liquid drink mixer adapted to operate in a Mason jar and to be slidably mounted in the jar cap.

Another object of the invention is to provide a portable churn of the reciprocating type, that may be either permanently connected to a threaded jar cap or which may be easily attached to the ordinary Mason jar cap.

A further object of the invention is to provide a churn provided with a plurality of paddle shaped agitating members adapted for movement in a vertical arc.

Other objects and advantages of the invention will become apparent from the specication of which the drawing forms a part, and wherein:-

Figure ll is an elevational view of the device mounted in a Mason jar,

Figure 2 is a. fragmentary elevational view partly in section illustrating the range of movement of the agitators, and

Figure 3 is a bottom plan view of the agitators in assembled position.

Referring more particularly to the drawing wherein like referencecharacters designate like or corresponding parts in the different views, I0 is a Mason jar shown in dotted lines, and provided with a screw cap II in which is slidably mounted a rod I2 provided at its upper end with a handle or knob I3.

Cap II is shown provided with a sleeve I4 in which rod I2 is mounted, and which is adapted to form a guide for the rod I2 as it reciprocates. However, rod I2 can also be mounted in an opening in a cap I I which is not provided with a sleeve To the lower end of rod I2 is secured disks I5 and I6 mounted in spaced relationship one above the other. The lower end of rod I2 is threaded, and disks I5 and I I5 are provided with threaded openings to permit the adjustment of the space between the disks I5 and I6.

Agitators Il are provided with offset loop portions I8 adapted to pivotally engage openings IS in disk I5 to mount the agitators in spaced relationship around the disk I5. The lower ends of the agitators I'I are provided with enlarged paddle shaped portions 20 which are flared outwardly. 'I'he upper ends 2I of agitators I 1 are bent inwardly and normally engage against the under face of disk IE.

In operation the device is slidably mounted as shown in Figure 1, and the jar I0 is lled with the ingredients to be mixed. Handle I3 is grasped and rod I2 is reciprocated in cap II. As rod I 2 moves upwardly the agitators II remain in their normal positionas shown in Figure 1. As rod I2 moves downwardly the pressure of paddles 20 against the contents in jar I0 causes the paddles 20 to move outwardly to the position shown in dotted lines in Figure 2. The movement of paddles 20 is limited by the ends ZI engaging disk I6 and disk I5, as shown in full and dotted lines in Figure 2. Handle I3 can be removably connected to rod I2 so that it can be removed to permit the removal of rod I2 from cap II.

It is to be understood that only the preferred embodiment of the invention has been shown, the right being reserved to make such changes and modications as will not depart from the spirit and scope of the invention as claimed.

We claim as our invention:-'

1. A mixer comprising a threaded rod, disks adjustably supported on the threaded portion of said rod, one of said disks being provided with4 a plurality of spaced openings, agitators pivotally engaging said spaced openings, said agitators being mounted to swing through an are and having their upper ends bent inwardly to move between said disks to limit their movement thereby, and said disksv being adjustable to vary the length of movement of said agitators.

2. A mixer comprising a rod, disks mounted in spaced relationship on said rod, one of said disks being provided with a plurality of spaced openings, agitators bent intermediate their ends to form a loop portion, said loop portion pivotally engaging the opening in said disk, the lower ends of said agitators being enlarged to form, paddles, and the upper ends being bent inwardly to move between said disks to thereby limit the move- Vment of said paddle portions.

3. In a mixer, a vertically reciprocating rod, plates adjustably mounted on said rod, one of said plates being provided with a plurality of spaced openings, and agitators pivotally mounted in said openings, intermediate of their ends, the upper ends of said agitators being bent to extend between said plates and to be limited in their movement thereby, the lower ends of said agitators being normally disposed substantially parallel to said rod, said lower ends being enlarged and flared outwardly at their lower edges causing the agitators to be opened by the downward movement of said rod.
